Results of deep dredging off the Mull of Galloway, 23 



I beg, in connexion with this and the preceding catalogue 

 (by Mr. Hyndman), to call the attention of naturalists in- 

 terested in the study of the Mollusca to the results obtained 

 in a third locality on the western coast of Scotland — at Oban 

 — by Mr. Jeffreys, published in Sowerby's ' Malacological 

 Magazine ' (No. 2, 1839). Mr. Jeffreys obtained * Tere bra- 

 tula aurita§ plentifully in about 15 fathom water," and along 

 with it found u Crania personata not uncommon." He pro- 

 cured also the three species of Lima — L. tenera, L. fragilis, 

 L, subauriculata — taken off Sana Island. Nucula minuta was 

 dredged at Oban as well as off the Mull of Galloway ; it has 

 been procured on different occasions by deep dredging in Bel- 

 fast bay, and many years ago was found at the Giant's Cause- 

 way. The Myrtea spinifera, of which a single valve was 



* No Algce were brought from any of the three depths. 



f These numbers denote the different depths at which the species of 

 Zoophytes were found ; No. 1. at 50, No. 2. at 110, No. 3. at 145 fathoms. 



% S. margarita, Hassall, seems to be identical with this. My specimen 

 is without vesicles. It agrees with the description and magnified figure of 

 Solander and Ellis better than the figure of natural size. 



§ This species was dredged in Belfast bay by the collectors attached to 

 the Ordnance Survey.
